Symmetries and Degrees of Freedom in Cosmic Epochs of Accelerated Expansion
Due to the worldwide COVID-19 lockdown Boğaziçi Physics department has transferred their weekly departmental series, hosted by Prof. Can Kozcaz into a series of online open public seminars. It was a great honor to be part of this series with
Due to the worldwide COVID-19 lock down Monday Meetings was initiated by İ. Ceyhun Andaç, a PhD student at Istanbul Technical University and Universite Granoble Alpes, to come together and listen to each others works via an online platform. The
We discussed new directions considering wavefunction calculations on de Sitter with Dionysios Anninos and Paolo Benincasa who were also interested in our recent work on unitary representations at the late time boundary of de Sitter.
Our results on the unitarity at the late time boundary were presented and discussed upon at the group meeting of Andrew Tolley and Claudia de Rham, together with possible questions to raise next.
As our first concrete step we have identified boundary fields on de Sitter for scalar fields of various masses in terms of the irreducible representations of the (d+1)-dimensional de Sitter symmetry group SO(d+1,1). One can think of these irreducible representations as particles
On October 1st 2019, the project SymAcc, which receives funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 840709 started.
The start of our project was announced at the FZU with the following article.
